There is a dimension of Zlatý kůň’s existence that no genomic analysis, no facial reconstruction, and no archaeological study can reach: language.

She almost certainly had language.

The cognitive architecture required for human language — the capacity for syntax, for arbitrary symbolic reference, for the recursive embedding of propositions within propositions — is present in anatomically modern humans by the time of Zlatý kůň, and there is growing consensus that it was present much earlier in the modern human lineage.

The cultural complexity evidenced in Upper Paleolithic sites — the planning, the transmission of technical knowledge, the symbolic behavior — is consistent with full linguistic capacity.

But what language she spoke — what words she used, what grammatical structures organized those words, what the phonological inventory of her speech community was — is completely beyond recovery.
